9. A shelling facility for chestnut processing as claimed in claim 1, wherein said blanking unit (700) is provided with a plurality of parallel discharge hoppers positioned relative to said sorting frame.
10. A method of using a shelling apparatus for processing chestnuts as claimed in any one of claims 1 to 9 wherein said shelling apparatus for processing chestnuts is used comprising the steps of:
s1: preprocessing Chinese chestnuts: freezing raw chestnut to be processed for 2.0-2.5h to obtain frozen chestnut for later use;
s2: chinese chestnut feeding: pouring the frozen chestnuts onto a conveyor belt body (220) at the lower end of a conveyor belt mechanism (200), driving the chestnuts to ascend upwards in a row shape by support bars (230) on the conveyor belt body (220), and inputting the chestnuts into an extrusion mechanism (300);
s3: and (3) breaking the shell: the chestnuts distributed in a row shape enter the lower rubbing plate (340), the lower rubbing plate (340) is driven by the cam arm body (350) to be lifted upwards and move forwards, meanwhile, the upper rubbing plate (310) moves forwards under the action of the hydraulic rod (320) at the moment, so that the frozen chestnuts roll and are squeezed between the two rubbing plates, the concave table (312) on the upper rubbing plate (310) can clamp the upper surfaces of the chestnuts, the reducing rolling grooves (341) of the lower rubbing plate (340) clamp the lower surfaces of the chestnuts, the two rubbing plates move relatively to drive the chestnuts to roll and squeeze along the reducing rolling grooves (341), so that cracks are generated on the shell, the chestnuts are rolled and squeezed on at least two sides in the reciprocating movement of the lower rubbing plate (340), so that cracks are generated between the fruits and the shell, and the connection relationship between the fruits and the shell is unstable when the cracks are generated by squeezing because the fruits and the shell are separated during freezing, is easy to be separated;
s4: fruit and shell separation: the chestnuts processed by the operation of S3 enter two oppositely arranged press rollers (420), rubber roller hair is arranged on the outer wall of each press roller (420), the roller hair rotates oppositely to drive the unstable connection relation between the chestnuts and the shells to be in a separation state, and then the chestnuts are thrown into a sorting mechanism (500);
s5: separating fruit peels from fruits: pumping out saline water from a water tank (620), heating the saline water through an electric heating spraying disc (610), and freely spraying from top to bottom, wherein the hot saline water meets the shelled and frozen Chinese chestnut, so that fruit skins attached to the surface of the Chinese chestnut are curled and separated from the fruits, and the fruits are guaranteed to be complete and clean;
s6: fruit sorting and discharging: the peeled fruits roll out through different gaps in the sorting cage (510), and then are output through a blanking part on the blanking mechanism (700), and the shells and the peels are driven by hot salt water to be flushed into a water tank (620).
